Hybrid Approach for Optimizing Process Parameters in Biodiesel Production from Palm Oil

Abstract:

Biodiesel was synthesized from direct transesterification of palm oil reacted with methanol in the presence of a suitable catalyst. There is a sequence of three consecutive reversible reactions for the transesterification process. These process parameters were optimized via the hybrid optimization approach of a conventional response surface method and artificial intelligence mechanisms from Sine Cosine and Thermal Exchange Optimization metaheuristics. The influential parameters and their combined interaction effects on the transesterification efficiency were established through a factorial designed experiments. In this study, the influential parameters being optimized to obtain the maximum yield of biodiesel were reaction temperature of 60–150°C, reaction time of 1–6 hours, methanol to oil molar ratio of 6:1–12:1 mol/mol and weight of catalyst of 1–10wt. %. On the first phase, the analysis of variance (ANOVA) revealed the reaction time as the most influential parameter on biodiesel production. Based on the experimental results from the hybrid algorithm via the SCO, it was concluded that the optimal biodiesel yield for the transesterification of palm oil were found to be 100°C for reaction temperature, 4 hours for reaction time, 10:1 wt/wt of ratio methanol to oil and 8% of weight of catalyst with 92.15% and 90.97% of biodiesel yield for expected and experimental values, respectively.
